@shadow portal
Steam Instructions
Epic Games Store Instructions
If you have Everest installed, you will need to reinstall it after verifying.

dense cobalt Jan 29, 2026, 8:13 PM

#

Probably

shadow portal Jan 29, 2026, 8:13 PM

#

nah I don't have Everest

#

this is my first time launching the game

dense cobalt Jan 29, 2026, 8:13 PM

#

That's an aside to verifying game files

#

The links are what actually matters

shadow portal Jan 29, 2026, 8:14 PM

#

the Steam Instructions?

dense cobalt Jan 29, 2026, 8:14 PM

#

If you're on steam then yes

shadow portal Jan 29, 2026, 8:14 PM

#

maybe you can read the error message

dense cobalt Jan 29, 2026, 8:14 PM

#

Yeah

shadow portal Jan 29, 2026, 8:14 PM

#

pwease :3

#

I can't decipher this cryptic magic

vale plover <@1410524295548899459> [Steam Instructions](<https://help.steampowered.com/en/fa...

Ok sorry if my communication was too concise but the command is a reusable instruction to tell you to verify your game files since it looks like there's something wrong with your install, but since windows vanilla gets xna (a bad version of the game) you may have to switch to fna if it continues

#

I don't remember this error but it looks suspicious

shadow portal Jan 29, 2026, 8:16 PM

#

in what way does it look "suspicious"?

dense cobalt Jan 29, 2026, 8:18 PM

#

Having presumably corrupt game files soon after installing, though it could be a red herring and caused by xna

shadow portal Jan 29, 2026, 8:19 PM

#

I guess I have nothing to lose

dense cobalt Jan 29, 2026, 8:21 PM

#

Indeed as verifying game files does not make you lose anything

shadow portal Jan 29, 2026, 8:23 PM

#

nope still didn't work

#

I am pretty sure this isn't a corrupt file thing

#

Xinput?

#

controller?

#

but I don't have controllers connected

#

I just repaired XNA and Direct X

#

but still nothing

vale ploverBOT Jan 29, 2026, 8:26 PM

#

To switch to the version of Celeste using the FNA framework, go to your Steam properties for Celeste and switch to the opengl beta.
If you have Everest, you will need to reinstall it after doing this.

dense cobalt Jan 29, 2026, 8:26 PM

#

You should try using fna

#

Are you on x64 windows?

shadow portal Jan 29, 2026, 8:26 PM

#

yup

#

I have the public version by default

#

no way that's the problem

#

rightttttt...?

#

I guess I got nothing to lose

dense cobalt Jan 29, 2026, 8:27 PM

#

The windows default version is inferior basically to the beta used on every other os

shadow portal Jan 29, 2026, 8:31 PM

#

wait no way

#

it actually worked!

dense cobalt Jan 29, 2026, 8:31 PM

#

🎉

shadow portal Jan 29, 2026, 8:31 PM

#

thanks a ton :3

dense cobalt Jan 29, 2026, 8:31 PM

#

I'm getting multiple people are typing when you type, crazy code

shadow portal Jan 29, 2026, 8:31 PM

#

I don't even wanna know what the issue was atp THANKS

dense cobalt Jan 29, 2026, 8:31 PM

#

dense cobalt I'm getting multiple people are typing when you type, crazy code

Unless there's actually someone else

shadow portal Jan 29, 2026, 8:32 PM

#

meow

#

meow (x1)

#

meow (x2)

#

see multiple meows

#

multiple people

#

scary

dense cobalt Jan 29, 2026, 8:32 PM

#

Fair enough

alpine cave Jan 29, 2026, 8:34 PM

#

dense cobalt Unless there's actually someone else

That might have been me. I was trying to help them over on Reddit and ran into this thread. Not sure if I accidentally started typing here...

dense cobalt Jan 29, 2026, 8:36 PM

#

Good old r/celeste help posts where you probably won't be directed to the wiki or discord

#

Or was it celestegame

#

If anyone reads this, 'existance' is spelt existence...

alpine cave Jan 29, 2026, 8:40 PM

#

It was r/celestegame, which actually does automatically link the discord on tech support questions. Unfortunately, it does require selecting that particular flair

dense cobalt Jan 29, 2026, 8:40 PM

#

You said you're on the fna beta, am I thinking of something else or is that 1.3.3.0

alpine cave Jan 29, 2026, 8:40 PM

#

(Still have a memory of the first time I tried to find the sub and went to r/celeste... not going to do that again LOL)

alpine cave Jan 29, 2026, 8:41 PM

#

dense cobalt You said you're on the fna beta, am I thinking of something else or is that 1.3....

Yeah, that's the one

dense cobalt Jan 29, 2026, 8:41 PM

#

Uh

#

Are you playing a 5 year old build... Hopefully not

alpine cave Jan 29, 2026, 8:42 PM

#

It is actually v1.4.0.0, I believe

#

Not sure why it's listed like this

#

Actually, let me go open the game and check for sure

dense cobalt Jan 29, 2026, 8:43 PM

#

Interesting

#

It'd be weird if it was actually outdated

alpine cave Jan 29, 2026, 8:43 PM

#

Can confirm it's 1.4.0.0

dense cobalt Jan 29, 2026, 8:43 PM

#

But I guess there's a reason people recommend opengl here (idk)

#

I never actually checked the version beyond the listing lol

#

Maybe fna just runs on directx

alpine cave Jan 29, 2026, 8:44 PM

#

Yeah, I was pretty sure it was the right version on the title screen, but I got scared LOL

#

FWIW, selecting the XNA version also says the wrong thing

dense cobalt Jan 29, 2026, 8:45 PM

#

I wonder what picking xna on linux would do, cant test today

alpine cave Jan 29, 2026, 8:46 PM

#

Hmmm... good question. Doesn't that require setting up WINE/proton in a pretty specific way? I don't really remember, as I don't have any linux machines currently

dense cobalt Jan 29, 2026, 8:46 PM

#

Celeste can kinda well run with proton but theres usually no reason not to use native

#

Reminds me I was meant to look at why my everest log says no vulkan device found, and a few lines down says it's rendering the game with my vulkan...

#

alpine cave Not sure why it's listed like this

the beta-1.3.3.0 branches were for testing the changes that eventually became 1.4, however they can't rename or delete the branch without kicking people off of it and back to XNA by default

#

so they were just set to 1.4 and kept around
